Template:American Civil War

How to manage this template's collapsible groups/sections option

• This template includes collapsible groups/sections. When it first appears, one of these groups/sections may be set to be visible ("expanded") while the others remain hidden ("collapsed") apart from their titlebars. To achieve this, include the parameter |name where name is one of the following words that identify the groups/sections (omit any speech or quotation marks):
• "Origins", "CTCBS", "Leaders", "After", "RTC" or "Sisters"
• For example: {{American Civil War |Leaders}}
